Answer:
360
Step-by-step explanation:
The given digits are 1,2,3,4,5,6.
So, total number of digits = 6.
We need to find the number of different ways to form four-digit numbers using the digits, without repetition.
Total ways for first place = 6
After selecting 1 digit the number of remaining digits is 5. So,
Total ways for second place = 5
Similarly,
Total ways for third place = 4
Total ways for forth place = 3
Total number of ways =
Therefore, 360 four digit numbers are possible.
Given:
The table of values of an exponential function.
To find:
The decay factor of the exponential function.
Solution:
The general form of an exponential function is:
...(i)
Where, a is the initial value and is the decay factor and
is the growth factor.
The exponential function passes through the point (0,6). Substituting in (i), we get
The exponential function passes through the point (1,2). Substituting in (i), we get
Here, lies between 0 and 1. Therefore, the decay factor of the given exponential function is
.
Hence, the correct option is A.
